I have a problem with a Briggs toilet. I have replaced the wax ring 5 times and it still leaks. I think thetoilet must be made wrong because each time I remove the toilet the old wax ring has been squashed to the point of leaving no wax above the flange.The flange is above the floor about 7/16" and the toiletbase is 1/2" below the bottom of the toilet. Any Suggestions?
